Definitions
- the present invention relates to a track with closed-ring ropes, of the type consisting of adjoining members, and which is obtained by connecting adjoining members to each other.
- Said tracks can be installed on a number of industrial vehicles, provided for instance with buckets, excavators, hammers and similar devices.
- Closed-ring tracks only consisting of metal members hinged to one another, and which have the disadvantage of being noisy and of damaging streets, are known.
- the track described in the utility model application no. MU96/U000445 filed by the present applicant consisting of a track made up of members connected to each other by means of ropes fastened to the members by bolts, offers the advantage of having a long life and of supporting heavy loads without track's elongation, however its construction is expensive since the assembly of the various parts takes longer.
- the track with ropes of the present invention allows the above-mentioned drawbacks to be eliminated and is especially advantageous because its construction and assembly are simple, and the connection of both ends of each rope can be easily accomplished, thus making the track cheaper than the known types.
- the track 10 having the features which will be described in detail hereinafter, is wound in the shape of a closed ring onto a driving gear wheel 11 and onto idle pulleys 12.
- a similar track, not shown in the figure, is parallel to and adjoining the above track 10 so that pulleys 12 hold a frame 13 provided with a support 14 carrying a control cabin (not shown), which in turn is connected with tools such as buckets, excavators, hammers and the like (also not shown).
- the present track comprises members 15 whose opposite ends carry one or more metal ropes 16 and 17 which are wound according to the development of track 10.
- Said members 15 have through-holes 18, 19 housing ropes 16, 17, which are in their turn fastened to members 15 by heading of the members near said holes 18, 19.
- Each couple of members 15 creates a central space 20 for coupling with the driving gear wheel 11.
- Said fastening of ropes 16 and 17 to members 15 by heading is accomplished by means of an implement 21 provided with projections 22 which, upon lowering of the implement, form headings 23 on the upper surface of each member 15, thus resulting in the fastening of ropes 16 and 17 to said member.
- both ends 16', 17' of each rope are arranged next to each other and housed in one or more socket members 15', similar to members 15, with said ends 16', 17' of each rope housed in two adjoining holes 18, 19. Also in the case of ends 16', 17', the fastening of the latter to the socket members 15' is accomplished by heading members 15' near the adjoining holes 18 and 19 by means of the implement 21.
- each socket member 15' On the opposite sides of each socket member 15', the ends 16' and 17' of each rope are brought closer to or spaced from the other rope or ropes housed on the same side of each socket member 15'.
- the metal frame consisting of members 15 and 15' and of ropes 16 and 17 fastened to said members is contained in a rubber cover having an external tread part and an internal part shaped in such a way as to leave a central space 20 between each adjoining member for coupling the teeth of the driving wheel 11 to said members 15 and 15'.
